To all whom it may concern:

Be it know-nthat I, WILLIAM R. l-lunsnr,

a citizen of the; UnitedStates, residing at Birmingham, inthe county of J elferson and State of Alabama, have invented certain new and useful Improvements in Flush Valves,

of-which, the following is a specification.

invention relates to flush tank appa- 'ratus, and the principal objects of the invention are to provide means for locking the fioat in ltS' IZLlS Gd PQSltlOII, for locking the outlet valve in :its raised position dur- "ing the descent of the float, and jfor automatically openingsaid outlet valve incase the water level in .the tankrises above a pre-determined point.

:thlS specification, and in which,

"ity than water can be substituted. y

In order that theinvention maybe readily understood, reference is had to they accompanying drawings, forming a part of Figure l is a vertical sectlon through a 'flush tank showing my improved valve mechanism therein,the operative parts beas ing showninelevation;

In"this'figure the parts areshown in normal position Fig. 3 is a view similar to Fig; 2, showing "the position which A the parts assume when the'wa ter reaches an abnormal level;

Fig. 2, looking the direction of the Referring to the drawings in detail, X designates a tanlqwhich may be of any suitable construction, and in which is located the usual float A. This float is operatively connected with the valve mechanism designated in its entirety by the reference character 3 and controlling the flow of water from the in- .let pipe C, and its discharge from the outlet D. The tankis operated by any suitable lever F, connected with the outlet valve lever by means of a chain E.

My improved valve 1 operating mechanism'comprises a supporting bracket having a base 1, secured to the bottom of the tank, and spaced parallel side members 2, as clearly shown in Fig. ,7. The inlet valve is of the shape shown inFig. 6, and comprises a central portion'or valve proper 3, which may be lined with 'a suitable soft material and which is adapted to fit down over the upper end of the inlet pipe C. A At one side of thevalve 3 projects a bifurcated portion 4, which is pivoted to a pin 5, secured to the frame members 2. The other end of the valve member terminates in a pair of spaced arms 6'6, as clearly shown in the draw- (r and as hereinafter more fully referred to. The float A is secured toa float-operated lever f, having at its lower end a body portion orblade 8, pivoted at 9 to a pin which is supported in the frame 2. In the lower part of the body 8 is secured a pin 10, which extends between the arms 6-6 of the inlet valveand serves to operatethis valve as the float rises and falls, as will be evident. The upper edge of the body 8 has at its forward corner a'toe 11, which is'adapted to engage a'hook 12,.the rear portion 13 of which is pivoted on thepin 5 between the bifurcated end 4, of the inlet valve. This hook is freely movableand' operates under the influence of gravity. The body 8 also has a heel 14, the purpose of which will be hereinafter more fully described.

Also'pivoted to the pin 9 alongside of the lever 7 s the outlet valve lever 15, carrying at its end the outlet valve 16, secured to the ,lever in any'suitable way, as by means of a bolt and nut 17." The valve 16 preferably consists of'a disk of some heavy material, such as lead, and may,"if desired, be pro- "vided with'a facing 18 ,of soft rubber, or the like. This valve seats uponthe flange 19 of the outletv pipe D and forms therewith a watertight joint a whereby only one lever can be held at a time.

5. In a device of the character described, the combination with an outlet valve lever and afloat operated lever mounted side by side, a single hook adapted to engage both of said levers and hold them in raised position, and means for causing said hook to release said float lever before engaging said outlet valve lever.

6. In a device of the character described, an outlet valve lever and a float operated lever pivotally mounted side by side on a common center, a hook ada ted to engage said outlet valve lever to hol it in its raised position, and said float lever having a heel arranged to trip said hook out of engagement with said outlet valve lever when the float approaches its lower position.

7. In a device of the character described, an outlet valve lever and a float operated lever pivotally mounted side by side on a common center, a hook adapted to engage said float lever to hold it in its raised position, and said outlet valve lever having a nose arranged to trip said hook out of engagement with said float lever when said outlet valve is moved to open position.

8. In a flush tank apparatus, an outlet valve lever and a float operated lever pivotally mounted side by side, and a connection between said levers permitting independent movement thereof within normal limits, said connection serving to cause said levers to move together when the float lever rises above its normal position.

9. In a flush tank apparatus, a float operated lever and an outlet valve lever independently pivoted about a common center, and connections between said levers whereby movement of the float operated lever to abnormal position serves to shift the outlet valve lever in the opening direction.

10. In a flush tank apparatus, the combination with an inlet valve and outlet valve, a lever to which said outlet valve is attached, a float lever, said levers being pivoted about a common center, a pin carried by said float lever and operatively connected with said inlet valve, said outlet valve lever having a slot in which said pin engages, said pin and slot being so related as to permit independent movement of said levers during the normal operation of the apparatus but serving to impart an initial opening movement to the outlet valve when the float lever rises beyond a predetermined position.

In testimony whereof I have aflixed my signature.

WILLIAM R. HURSEY.
